Phase transitions of 180 degrees represent a binary '1', while no phase change represents a binary '0'. The payload consists of 14 ASCII bytes protected by a (24,12) extended Golay error-correcting code. When all 14 rows are assembled, the matrix forms an 80-column ASCII status report. -- === Amy Tanaka === Dept of Electrical Engineering, University of Illinois Urbana-Champaign "Hardware is temporary.
